Thailand’s oldest seaside national park. Limestone Mountains rising steeply as high as 605 meters make this part of the coast especially beautiful. Sam Roi Yod is a one hour drive south of Hua-Hin. We stop on the way to look at a pineapple plantation then continue driving for another ? hour to the fishing village Ban Bang Po where we enter a fisherman’s boat and cruise along a canal out to the sea. At Laem Sala beach we climb 430 meters up the mountain to Phraya Nakorn Cave. There is a hall where light comes in through a sinkhole. King Rama V was so impressed with the cave he built a beautiful pavilion inside and revisited it several times. After lunch, relax on the beach before we return to hotel.
